What red flags suggest an appraiser is not trustworthy?

Be cautious if an appraiser offers to buy the item right after valuing it, especially if the price feels rushed. That is a conflict of interest, and the low value may be setting up the purchase. The same goes for anyone who bases the fee on a percentage of the appraised value.

Other warning signs include refusing to provide a written engagement agreement, being vague about credentials or training, promising a high number before seeing the item, or delivering a report with no descriptions, photographs or explanation of method.

A trustworthy appraiser explains the purpose and type of value, states fees up front, and stays within their area of expertise. If they are not qualified in a category, a good one will say so and refer you to a specialist.
